In this paper, the continuous cooling transformation (CCT) curve of test steel is determined with FORMAS-TOR-F full automatic phase transformation instrument by taking low carbon medium manganese steel as the object of study. The results showed that the microstructure at room temperature was proeutectoid ferrite + pearlite when the cooling rate was 0.1~0.5 ℃/s; when the cooling rate was 1~2 ℃/s, there was granular bainite and the microstructure at room temperature was ferrite + pearlite + granular bainite; when the cooling rate was 5~10 ℃/s, the bainite gradually transformed to martensite, so the martensite increased continuously and it was the mixed microstructure of martensite + bainite at room temperature; when the cooling rate was greater than 10.0℃/s, it was martensite structure at room temperature, which provide references for formulating heat treatment process.

文章以低碳中锰钢为研究对象，利用FORMASTOR-F全自动相变仪，测定了试验钢连续冷却转变的CCT曲线。结果表明：冷却速度为0.1~0.5 ℃/s时，室温组织为先共析铁素体+珠光体；冷却速度为1~2 ℃/s时，出现粒状贝氏体，室温组织为铁素体+珠光体+粒状贝氏体；当冷速为5~10 ℃/s时，贝氏体逐渐向马氏体转变，马氏体不断增加，室温下为马氏体+贝氏体混合组织；当冷速大于10.0 ℃/s，室温下为马氏体组织。为热处理工艺的制定提供了参考依据。
